On the surface this seems an odd question so I'm sure there is
misunderstanding.<br>
<br>
CM needs access to DNS to perform forward and reverse lookups on:<br>
SIP endpoints<br>
h323 endpoints<br>
AD servers<br>
other nodes in the cluster<br>
<br>
There are deployments which do not use any of these and therefore do
not need access to a DNS server. On those, DNS can be disabled.<br>

service is enabled on both CUCM and Unity servers which I don’t quite
understand why is needed. The Services URL on CUCM is pointing to load
balancer IP. Would there be any other reason we have to enable DNS
client on CUCM and Unity server? Also is there a load impact by
enabling DNS client service?</font></p>
